what power range are you trying to improve? timing will give you more starting low, and the cool head can bump you up all over, but reed selection really depends. boysen pedals come in different ranges, and for about 50 bucks, give or take, you can pick either some stiffer pedals that flow best on top end, like dual stage carbon fiber, or some softer dual stage pedals that perform better on the low-mid. if you port, then you can step up to the vf3's for top end, or chariot's for more range selection. Once you get your mods tuned in, then decide what, if any, sprocket changes you may want. I believe that noss also offers a discount for bhq members :thumbsup:
